Research on Idler Collapse Resistance under the Influence of Material Factors
Collapse resistance is the basis for studying conveyor energy loss,and the collapse resistance between the conveyor belt and the idler accounts for more than 60％of the running resistance,so it is of great significance to carry out the conveyor belt collapse resistance.Firstly,a simulation kinetic model is established in Abaqus according to the specifications and dimensions of the actual round pipe conveyor.Secondly,considering the idler collapse resistance under the filling rate of nine different materials,the expression on positive pressure is fitted.Based on the variation law of collapse resistance under the influence of six different material densities,the fitting formula of collapse resistance was obtained.Summarize the expression of collapse resistance with respect to positive pressure;Finally,other influencing factor values are selected to verify the accuracy of the collapse resistance expression,and the maximum error is 3.28％,indicating that the established collapse resistance expression has high accuracy.
